THOMAS J. BLAKE, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR OF ONE- HALF TO JOHN BATH, OF SAME PLACE.

GRAIN-SCOOP.

SPECIFICATION formingpart of Letters Patent No. 255,483, dated March 28, 1882.

Application filed September 27, 1881. (ModeL) To all whom it may concern Be it known that I THOMAS J. BLAKE, of Pittsburg,in thecounty ofAllegheny andState ofPennsylvania, have invented certain new and useful Improvements in-Grain-Scoops; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same,

reference beinghad to the accompanying drawin gs, which form a part of this specification, in which- I Figure 1 is a plan of the blank blade. Fig.

2 is a front view of the blank after pressing and crimping. Fig. 3 is a section, an x, of Fig.

'2. Fig. 4 is a back view of a scoop made according to the old form. Fig.5 is a front view of my improved scoop with front strap in position. Fig. 6 is a back view with back strap in position. Fig. 7 is a side view of the complete scoop. Fig. 8 is a front view, showing modified straps in one piece with the tang.

Fig. 9 is an edge view,and Fig. 10 aside view,

of same bent to shape. This invention relates to what are commonly known as grain-scoops. These are at present constructed in various ways. One wayis to take a blank of aboutthe form shown at Fig. 1 and cut out a triangular piece, which leaves a gap extending into the blade at through the back I), as shown by dotted lines in Fig. 4. The straps have triangular enlargements sufficient to cover this gap; but in coverin git they must necessarily extend down over and under the blade, and are secured by rivets, as shown, one rivet at the point being necessarily on the bottom or blade. Such a scoop rapidly wears out from the grinding friction of the bottom strap and rivet on the floor or ground. Another way is to cast a special ingot, which is rolled out in such manner that the straps and blade are integral and rivets dispensed with. This process is costlyin requiring an extensive plant of machinery to be erected for it. Another wayis to crimp upthe back without cutting, thereby corrugating the back into a sort of socket for the handle. 7

My invention is different, and consists in the hereinafter-described construction, whereby I 50 avoid cutting into the blade, and avoid the conshown.

sequent necessity of extending the straps onto the blade to cover the gap, and avoid the blade rivet or rivets.

I take a blank of any suitable shape, such as shown in Fig. l or that used in Fig. 4, except that the gap does not extend onto the blade a, and bend it up so as to form the blade a, sides 0, and back b by any of the well-known means. Holes 6 are punched in the back b,as

The straps are made of sheet metal, preferably. The frontstrap,f, widens out where it meets the back I) of the scoop, spreading in both directions laterally, so as to cover a portion of the back I), as in Figs. 5 and 8, and is bentso as to fit the ooncavityot' the frontfaee of the back I), the wide portion of the strap f being convexed at s in the middle to help form a socket for the handle and strengthen the whole for lifting. The back strap, g, is also formed to widen out and fit the back b,but at the part facing the convex or corrugation s of strapfis oppositely curved, as at i, Fig. 6, so that the recess between 8 and i will form a socket for the handle, diminishing to nothing at the lower end, and terminating, as do both straps,ata point on the back b above itsjunction with the blade a. Rivets are then set in the holes and headed up. Then the handle A is set in and attached in the usual way.

Such a scoop has several advantages. The back strap does not project onto the blade underneath, nor pass beyond the junction of blade and back. Oonseq uentl y, no matter how the scoop is tilted while in use or broughtinto contact with the floor or ground, there is no possibility of the rivets or back strap wearingout from friction. The combination of the curves 2' and s in the straps and their curved fitting to the back I) renders the scoop stiff and strong. a

For tang-scoops I weld the strapsf and g to the form shown at Figs. 8 and 9; but a more convenient way is to cast them complete in malleable iron, place a sheet of metal between the strapsfand g, and press or hammer to the 5 form shown at Fig. 10, and then remove the sheet of metal. This produces the same formation as if the straps were separately shaped and welded to form the tang.

I do not claim any particular way of form- I00 ing the blade, as my invention is to the combi- I cured to the scoop by rivets passing through nation of straps shown with the blade and handle.

What I do claim is- 5 In a grain-scoop, the combination of a blade, (1, having the high curved back 1), front strap, f, corrugated at s and extended laterally to fit thecurvatureof back b,back strap, g,corrngated at 17, fitting the back b laterally, and extending 10 only to a point on the back b above its junction with blade a,said strapsfand 9 being sei them and the back b, and a handle, A, attached to the said straps, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in presence of two witnesses.

THOMAS J. BLAKE.
